' |MPRovEMENT IN WASHING-MACHINES.

The Schedule referred to in these Letters Patent and making p art of the same.

To all whom it may concern Be it known that I, GEORGE. W. Hnnennnonn, of Chicago, in the countyr of Cook and State of Illinois, have invented certain `Improvements inT Washing Machines, of which the following is a specification, reference being had to the accompanying drawing.

Myinve-ntion relates to washing-machines, and consists in suspending within a box ot'novel construction,

pendulum-hammers of a peculiar shape, with rods for operating them, so connected to thehandles of the hammers as to adjust thc stroke fof the latter, as

hereinafter explained. In the drawing- Figure 1 is a longitudinal lvertical section of the machine1 and Figure 2' is a top plan view. l

In constructing this machine, a box, A,is made, with its sides parallel and its bottom and ends curved, as shown in fig, 1. Y

On its upper side are mounted standards or-fi'am'cwork B, from which are suspended two pendulumhammers, C and D, within the box, by -handles or arms a and b, as clearly showuin figr 1.

rlhe sides ofthe hammers' C and D are parallel with each other and with the sides ofthe box, and between. their sides are arranged, at'short distances from each other so as to leai-'e an intervening space,

a series of boards', AE; as clearly seen in fig. 1. l These boards are also s o arranged as to have their outer edges ona line running-at an angle withthe one made by the handles ou which the hammers are suspended, so that, as theliammers are swung in either direction, the linevof the outer edges of these boards will be nearly parallel with the end of the box opposite.

The opposite sides of the box A are extended at one end far enough to afford bearings F for a double crank-shaft c, as clearly shown in4 both figures.

Tothe cranks of 'this shaft are connected pitmanf' rods-d, their opposite'ends having pi-vote'dzto them sleeves, G, through which rthe handles of the hammers pass, as clearly shown in iig. 1. i

These sleeves may be fixed at different heights on the handles, by-Inea-us of agib and setscrew," Las shown inboth figures, and. in this way the' stroke'of the hammers be adjusted.

The shaft c may have an suitable gearing, H, con-- nected, for convenience in operating.v r

In operating this machine, the clothes or other ar'- ticles to be washed are thrown in the box A` on either side of the hammers C D, with suchl water and soap as may be preferred. A A

lhe crank c is then turned, and in being turned itgives alternate motions to the rods d,- and through them to the hammers (l and D. n

These hammers,'as they swing hack and forth, manipulate the articles being washed, in the same manner as a cloth-fullin'glmill, forcing' the waterfrom them at one time, withdrawing it at a1 1o'ther,- pressing and relaxing, and then, byreas'on of the form of the box, tnrningthem over at the saine time, and in this way thoronghlyrwashing them.

.Having thus described my invention,

In a washing-machine 'having pendulumhammers therein, the sleeves G, when arranged on the pendu- ]umrods of 'the hammers so as to be adjustable, substantially ns herein described and for thepurp'ose set forth...
